Equally spaced data : finite difference operators and their properties, Gauss’s forward and backward, Sterling’s formulae – Inverse interpolation – Hermite interpolation.

Differentiation : Finite difference approximations for first and second order derivatives.

Integration : Newton-cotes closed type methods; particular cases, error terms – Newton cotes open type methods – Romberg integration Gaussian quadrature; Legendre formulae.

Solution of nonlinear and transcendental equations: Regula Falsi method, Newton-Raphson method, Newton Raphson method for system of nonlinear equations.
